The clinical condition involving dental implants, characterized by soft tissue inflammation, bleeding, suppuration and rapid bone loss is widely known as peri implantitis. The main objective in the treatment of peri-implantis is to arrest the progression of the disease and at the same time to keep the dental implant in the mouth solving the inflammations signs of bleeding and pain. The aim of this paper is to highlight the effectiveness of the use of titanium brush and antimicrobial photodynamic therapy (aPDT) to decontaminate the implant surface, in association with regenerative procedures by means of autologous bone and demineralized bovine bone mineral (DBBM) in the treatment of peri-implantitis defects...

E. faecalis appears in many tooth root infections and is not eliminated by root canal therapy. It can reside in tooth root canals and the surrounding bone. This species may vegetate in bone after extraction of an infected tooth and colonize a dental implant after placement in the healed site. A colonization may cause fixture loss or marginal bone loss. These colonizations are generally multi-bacterial and pathogenic properties can be shared via plasmids. However, E. faecalis is not detectable with some culture techniques and thus can be missed...

No well-established evidences supporting the safe use of Bisphosphonates (BPs) or others antiresorptive agents prior, during or after dento-alveolar surgery, are currently available; moreover, the real risk of osteonecrosis of the jaw (ONJ) development is still unknown. The aim of the present systematic review was to assess the scientific literature concerning the implants placement in antiresorptive agents-users and the related risk of implants failure and ONJ development. English papers published from January 2003 until December 2014 were identified on Medline database...

Sleep bruxism and higher clench index have been associated with obstructive sleep apnea (OSA). However, there is no study that reports on the prosthetic complications in patients with OSA. Patients' records, who had performed a sleep study to diagnose OSA, were examined for the occurrence of prosthetic complications in implant-borne reconstructions. The primary outcome was the frequency of prosthetic complications. The secondary outcomes were anthropometric data, the type of the complication, type of the prosthesis, type of retention, number of supporting implants, number of prosthetic units, and the presence of obstructive sleep apnea...

Epidermolysis bullosa (EB) is a rare disease affecting the skin and mucus membranes, which is characterized by the formation of blisters in response to minimum trauma. The use of endosseous implants for fixed prosthetic restoration in patients with Recessive Dystrophic Epidermolysis Bullosa (RDEB) provides considerably better results than conventional methods using removable dentures. The objective of this clinical case is to describe the restoration of the full arch of an atrophic maxilla using endosseous implants and an implant-supported fixed prosthetic in a patient diagnosed with RDEB and exhibiting severe general and oral symptoms; and to evaluate improvements in the quality of life of the patient...

A fractured abutment screw of a crown supported by an endosseous implant is a complication. The fragment in the fixture can be retrieved with a festooned #557 latch burr set in reverse torque and subsequent clockwise turning #33 1/3 burr touched to the fragment side. The cemented abutment and crown can be salvaged by heating the crown/coronal screw fragment to 1000 degrees C for 20 minutes. Upon cooling, the crown and abutment can be then separated. A new abutment screw can then be used. The patient's diet, occlusal scheme and maximal bite force should be assessed...

This study focuses on the fatigue behavior and bone-implant attachment for the more usual surfaces of the different cp-titanium dental implants. The implants studied were: as-received (CTR), acid etching (AE), spark-anodization (SA) and with a grit-blasted surface (GB). Residual stresses were determined by means of X-ray diffraction. The fatigue tests were carried out at 37°C on 160 dental implants and the S-N curve was determined. The fatigue tests show that the grit-blasting process improves the fatigue life...

The aim of this in vitro study is to evaluate the effect of different levels of preparation of an implant abutment on its fracture resistance. The study evaluated abutments which incorporated a platform switch (Myriad plus abutments, Equinox Medical technology, Amersfoort, NL) and Standard abutments (BioHorizons Standard abutment, BioHorizons Inc, Alabama, USA). Each abutment was connected to an appropriate implant and was mounted in a self-cured resin base. Based on the abutment preparation depths, 3 groups were created for each abutment type - As manufactured; Abutment prepared to 1 mm apical to the original margin, and Abutment prepared 1...

Polyetheretherketone (PEEK) has been suggested as an alternative to replace titanium as a dental implant material. However, bioactivity and osseointegration of PEEK are debatable. Aim of this review is to systematically analyze studies that have compared PEEK or PEEK-based implants with titanium implants so that its feasibility as a possible replacement for titanium can be determined. The focused question was: 'Are the bioactivity and osseointegration of PEEK implants comparable to or better than titanium implants?'...

Reactive lesions of peri-implant mucosa are quite uncommon and the majority of them represent pyogenic granulomas and peripheral giant cell granulomas. The present paper describes the case of a 52-year-old woman with a tumor on the covering mucosa of a dental implant that appeared almost two months after implantation. An excisional biopsy was performed, under local anesthesia, and histologic findings were strongly reminiscent of a parulis. Mechanical trauma from the temporary removable denture in combination with the loosened cover screw, as it became obvious clinically and radiographically, may have acted as the stimulus for the inflammation...

The mandibular canal is a conduit that allows the inferior alveolar neurovascular bundle to transverse the mandible to supply the dentition, jawbone, and soft tissue around the lower lip. It is now acknowledged that the mandibular canal is not a single canal but an anatomical structure with multiple branches and variations. Iatrogenic injury to branches of the mandibular canal that carry a neurovascular bundle has been reported to cause injury to the main canal as severe as if the main canal itself is traumatized...
